Below i have listed few security measures to prevent problems (such as hacks, viruses etc) for your pc's.
- Check for Windows Updates and Office Updates regularly. Activate on Automatic Updates in the control panel and choose the appropriate options.
- Install a personal firewall, not the one that windows allows you to have. This can enhance the security to a new level.
- Install a spyware blocker. There are numerous softwares (some of them are free) that can scan and remove any spyware and speed up your computer once again.
- Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel / Administrative Tools / Services and you'll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. You have disabled spam pop-ups! Any good firewall will also stop them.
- For serious security reasons, change your passwords often. The reason for this is clearly because your password can get hacked. Change passwords for almost anything: Paypal, Yahoo Messenger, etc. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. Your password should look complicated but you should be able to remember it by writing on a piece of paper. The password should look like "155526ess". Therefore you have a high level of security against hackers.
- Have at all times an antivirus software, up to date. Most certain you will download many files from the internet and most of them have a virus or two. Having an up to date antivirus lowers the possibility of getting infected, the viruses getting imediately quarantined.
- If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get.
- Join a respectable e-mail security list.
- Find an IP proxy to protect your anonymity,
Be skeptical of things on the Internet. Don't assume that an e-mail "From:" a particular person is actually from that person until you have further reason to believe it's that person or it's one of your friends. Don't assume that an attachment is what it says it is. Don't give out your password to anyone, even if that person claims to be from "support."
Also to ensure your pc security is high, do not download just any file from the internet. Run a little scan beforehand.
Lately there have been rumors that hackers can now create a backdoor virus, bind it with a normal file and send it to just anyone, this leading to a total control over their computers. One last warning: Do not click on links before checking them beforehand. Secure your PC to ensure your data stays safe!
